This is the hair flip of a girl who's in charge.

The young royal — the Duke and Duchess of Cambridge’s middle child— is already exuding confidence at the tender age of four. In an Instagram video released by Kensington Palace, Charlotte calmly shakes the head of the lower school’s hand and then playfully flips her ponytail as the cameras click.

Her mother holds her backpack, which appears to be decorated with a key ring in the shape of a pony.

Now THAT is the hair flip of a child ready to take on the world. Or, at the very least, her first day at a new school.

Honestly, Charlotte always seems to have the best hair. So thick! So lustrous! We wonder if Prince William styled her hair for the first day, since he’s admitted before that he’s been working on his ponytail technique via YouTube videos.

Dad said Charlotte was thrilled to join George at Thomas’s Battersea, a private prep school in South London that focuses on kindness. “First day— she’s very excited,” Prince William told reporters, according to BBC.
